摘要：

During the injection molding process, whenever two distinct fronts of melted material join together they form a region where the material properties differ from those of the base material. By analogy with metal welding, this region is named a weld line, and it was observed that due to its morphology, failure of a component having multiple welding lines is most likely to occur within those regions. The experimental aspects of this paper are focused on the welding line damage behavior and the strain assessment was performed by means of Digital Image Correlation. Furthermore, the Cohesive Zone Model implemented in ABAQUS along with the Extended Finite Element Method was used for modeling the fracture behavior of the welding lines.
